Did you know you can tell the temperature by counting crickets chirps? The frequency of chirping varies according to temperature. To get a rough estimate of the temperature in degrees Fahrenheit, count the number of chirps in 15 seconds and then add 37. The number you get will be an approximation of the outside temperature.

Watch my video to see the challenge.

Complete the results table to check how accurate the crickets are.

You can then draw a graph of your results using excel or J2launch.  Create a line graph for your results and a range of other results such as half as many chirps, twice as many chips.  See what shape the results make on the graph. Now you can predict the temperature from any number of chirps.

Do grasshoppers and crickets have the same pattern?

Please share any results so we can check with the other children and see if it is the same for everyone.  Tweet results #Naturedays @DawnNaturedays or on the Nature days Facebook page.
